Three Phase Reference Standard Meter on-site meter tester with clamp CT class0.05

KE7308 Three Phase Reference Standard Meter

Accuracy : 0.05, Test method: clamp CT and 20A terminal input. It's light and small, which is convenient for on-site test. And it can be used to test the error of three phase energy meters and field electrical parameters of power grid. With a IP67 protection level, it can be used in many harsh condition.

Features:

1. Wide current range (direct connection): 0.05 A to 20A, the highest accuracy of each test point is 0.05%
2. Calibrate the error of all electricity energy meters, checking the constant of the energy meter
3. Simultaneous checking of the primary meter and the secondary meter in the same loop, or simultaneously checking of the active power meter and reactive power meter in the same loop
4. 7” color LCD display, All the parameters of each operation function can be displayed within one page
5. Two operation modes: touch screen and keyboard. Easy and reliable operation..
6. Measure voltage, current,frequency, power, power factor and phase angle
7. Simultaneous measure and display waveforms of three phase voltage and current
8. Measure ratio of CT.
9. Allocate clamp of 20A, 100A, 200A, 500A,1000A to directly measure the comprehensive error
10. Measure the 2^nd - 51^st harmonics of current and voltage
11. Display vector diagram, judge the wiring right or wrong automatically
12. Industrial grade engineering plastic suit case, which has a safety protection level of up to IP67.
13. Read the information of energy meter with barcode scanner (optional)
14. Battery, test lead power or external power for choices
15. Communicate with PC, download calibration data through USB flash disk, RS-232 port
16. Firmware can be upgraded through removed disk by users themselves
17. Save and browse the testing data
